  • Uh oh, they'll see right through me!
  • Step through, sir.
  • Why do you even have this thing?
  • Well one of the amazing purposes of xrays is for airport security.
  • It assists us in seeing inside people. Making sure there are no suspicious objects in sight.
  • Well how does it even work?
  • This beam travels through the air, comes into contact with our body tissues, and produces an image on a metal film. Soft tissue, such as skin and organs, cannot absorb the high-energy rays, and the beam passes through them. Dense materials inside our bodies absorb radiation.
  • Some people worry that X-rays aren't safe because radiation exposure can cause cell mutations that may lead to cancer. The amount of radiation you're exposed to during an X-ray depends on the tissue or organ being examined. Sensitivity to the radiation depends on your age, with children being more sensitive than adults.
  • Gee, you make it sound so amazing. There HAS to be a downside to xrays.
  • The most familiar use of x-rays is checking for broken bones, but x-rays are alsoused in other ways. For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer. When you have an x-ray, you may wear a lead apron to protect certain parts of your body. Airport security is not the only use of x-rays, medicinal is also a use.
